Application filed. April 5,

T 0 all whom it may concern Be it known that I, Arrrrron E. Huerms, a citizen of the United States, residing at Hoopeston, in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Pulping Machines, of which the following is a full, clear, ooncise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to pulping machines, having particular relation to machines oif this character wherein the material acted upon is sliced or out before being fed to the pulping mechanism, and it has for its object to provide an improved cutting means in combination with a machine of this character.

For a better understanding of my invention reference may be had to the accompanying drawings, in which;

Fig. 1 is a side, sectional, elevational view of a machine embodying my invention;

Fig. 2 is an end elevation-a]. view of the machine of Fig. 1;

Fig. 3 is a plan view of the hopper portion of my machine;

Figs. 4 and 5 are detailed views of the defiector member employed in my machine; v

Fig. 6 is a plan view of the cutter-head used in my machine; I

Fig. 7 is a sectional view taken on the line 77 Fig. 6; and,

Figs. 8 and 9 are views of a spindle which.

is employed in my machine for a particular purpose.

I find that it is extremely advantageous to slice vegetables and fruit which are fed to a pulping machine prior to their being forced against the screen or other means utilized to pulp the same. By slicing or cutting the material the strain on the screen is greatly relieved and a more thorough separation of the pulp from the skins and cores is permitted.

In the hereinafter described machine I 1920. Serial No. 371,197.

hopper and the pulping portion of the machine that a minimum amount of space is occupied thereby although each of the above portions functions in a satisfactory manner. Furthermore, I have so associated the cutter, the deflector and the feed-hopper that the aforesaid portions may be disassembled for the purpose of cleaning and for adjusting the knives. L Referring now to the accompanying drawings, standards 1 and 2 support the body of the machine 3 and, at the same time, provide journals for a main shaft a driven by a pulley 5, or other suitable means. Poss tioned at one end of the machine is a hopper 6 which is so arranged that the material after being acted upon therein is fed by means of a sloping portion 7 to one end of the pulping chamber. Inasmuch as the pulping chamber and the means associated therewith are more fully described and claimed in U. S. Patent No. 1,262,530, to H. W. Lowe, April 9, 1918, I will not further describe-this portion of the apparatus.

At one end of the shaft 4; is mounted a miter-gear 8 which meshes with a gear 9 secured to a spindle 10. The spindle 10 is provided with a shoulder 11, flattened portions 12 and 1.3, and a hollow seat 14:. A cutter-head 15 comprises a disk 16 having lugs 17 associated therewith which are adapted to fit over the flattened portions of the spindle 10 and to abut against the shoulder 11,.whereby the cutter-head 15 is rotated by the shaft 4 through the medium of the miter-gears 8 and 9. Knives 18 are mounted on the cutter-head 15 and are positioned adjacent apertures or substantially radial. slots 19 provided in the disk 16.

A deflector 20 comprises a supporting beam 21 having, on opposite sides thereof, notches 22 and 23 for the reception of bolts whereby said beam may be secured to the hopper 6, as shown. Depending from the beam 21 is a deflector member 24, here shown as of the helical type, and at the bottom of which is a restricted portion 25, which seats in the hollow portion 14 of the spindle 10.

Having now described one embodiment of my invention, the operation thereof is as follows:

The fruit, or other material to be pulped, is fed into the hopper 6 and because of the conjoint action of the deflector 24: and the revolving cutter-head 15, is sliced and passes downwardly through the slots or apertures 19. The sloping surface 7 guides'such sliced material into the pulping chamber, whereinit is further acted upon.

By reason of the relatively small number of parts employed in the hopper portion of my machine the cleaning thereof is comparatively simple, it being only necessary to loosen the nuts at 22 and 23 and thereafter bodily remove the deflector member 20 from the hopper. The cutter-head may then be removed by lifting the same from the flattened portions of the spindle 10..

Moreover, the arrangement showi'i ad nuts of a very compact arrangement of therequiredelements and allows the cutter-head to be driven directly from the main shaft.

l Vhile I have shown but one embodiment of my invention it is apparent that many modifications therein may occur to those skilled. in the art and I desire, therefore, that my invention be limited only'by the showing of the prior art orby the scope of the appended claims.

Having thus described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a pulp machine, a material receiving hopper, a cutter-head embodying knives and provided withapertures whereby said material is cut when brought therea'gainst, a guiding surface adapted to receive the material passing through said apertures and present the same to a pulping mechanism and a member adapted to be secured to said hopper having a deflector depending therefrom, said member being readily detachable to provide for thecleaning of said hopper and related parts.

2. In apulp machine, a material receiving hopper, a rotatable cutter arranged in said hopper, said cutter comprising-"an apertured disk closing the bottom, of the hopper and knives arranged in proximity to said apertures, whereby said material is deflected against said knives, sliced, and passed through said apertures and a member com prising an attaching beam'having a deflector depending therefrom into operative relation with said cutter, said member beingreadily detachable to provide for the cleaning of said hopper-and related parts. I

3. In a pulping machine, apulping mech anism, a shaft extending horizontally therethrough. a vertically-disposed spindle driven from said shaft throughmiter gears, or the like, and a cuttermounted on said spindle.

4. In a pulping machine, a pulping mechanisnua shaft extending horizontally therethrough, a vertically-disposed spindle driven from'said shaft throughmiter gears, orlthe like,'a material receiving hopper, and. a cutter mounted on said spin dle'in'the lower portion of said hopper.

5. In a pulping machine, a pulping mechanism,a shaft extending horizontally there through, a vertically-disposed spindle driven from said shaft through miter gears, or the like, a material receiving hopper, a cutter mounted on said spindle in the lower portion of said hopper, and deflector secured to said hopper for forcing the material against said cutter.

"6. In a pulping machine, a pulping mechanism, a shaft extending horizontally therethrough, a'vertically-disn0sed spindle driven from said. shaft through miter gears, or the like, a material. receiving hopper, a deflector suspendedtherein, an apertured cutter at the bottom thereof, and means for directing the material passing through said apertures into said pulping mechanism.

7. In a pulping machine, a pulping mechanism, a shaft extending horizontally therethrough, a vertically-disposed spindle driven from said shaftthrough miter gears, or the like, a material receiving hopper, a deflector suspended therein, an apertured. cutter at the bottom of said hopper, and means comprising a sloping surface surrounding a hearing member for said spindle for directing the material passing through said apertures into said pulping mechanism.

8. In a pulping machine, apulping mechanism, a shaft extending horizontally therethrough, a vertically-(lisposed spindle driven from said shaft through miter gears, or the like, and provided with flattened portions, a cutter having lugs engaging said portions and adapted to be driven thereby, a seat in. said spindle, a hopper arranged about said cutter, and deflector secured to said hopper and having a portion registering with said spindle seat whereby it is held stationary while said cutter rotates.

9. In a pulping machine, a pulping mechanism, a shaft extending horizontally therethrough, a vertically-disposed spindle driven fromsaid shaft through miter gears, or the like, a material receiving hopper, a cutter mounted on said spindle in the lower portion of said. hopper, and a deflector secured to said hopper for forcing the material against said cutter, said deflector comprising a beam adapted to be secured to said hopper and a helical deflecting surface depending therefrom and into proximity with said cutter.

In witness whereof, I have hereunto subscribed my name.
